| Compare high-level regional ruleset structures (tile deck size 136 vs 144 vs 152, hand length, and minimum Fan/point entry thresholds) across American, Chinese MCR, Japanese Riichi, and Hong Kong Mahjong. Do not use for Charleston passing steps, NMJL Joker meld legality, or Riichi Furiten checks. |
| Retrieve exact pre-game tile passing directions (Right, Across, Left), blind pass rules, and Courtesy Pass negotiation steps prior to the first discard in American Mahjong. |
| Validate whether an American Mahjong Joker tile can legally substitute inside a specific meld size (1 to 6 tiles) and retrieve exposed Joker live-turn swap rules. |
| Evaluate Japanese Riichi Mahjong discard/temporary Furiten Ron restrictions and verify whether a hand satisfies the mandatory 1-Yaku win condition independent of Dora. |
